Radio-controlled (or RC) helicopters are more than just child’s play. Many adults enjoy flying helicopters right along with their children, and in some cases, it even turns into a lifetime hobby. It is a pastime everyone can share, and besides the initial purchase of the helicopter, it is not very expensive.

Small helicopters designed for children come with only two-channel radios, the simplest design to fly. The most complicated ones feature seven or more channels to control all the gyros. Stores usually sell either toy helicopters or professional-grade replicas, but eBay sells both in the same place. The 3.5- and 5.5-channel helicopters are popular choices because they are affordable while still being able to perform many features that separate them from the rest.

Understanding Radio Channels.

Before discussing the technical aspects of how 3.5- and 5.5-channel radio-controlled helicopters differ, it is important to know how the radio channels work. Basically, every helicopter comes ready to go with a remote control. For simple helicopters, such as the 3.5-channel type, the remote control comes with the toy. Complex models that use a controller with 5.5-channels or higher require the consumer to purchase a separate remote control.

Channel Control.

The best way to think about how radio channels work is to think of each channel talking to the helicopter independently of the other. Because of this, each channel only controls a single function of the helicopter. Therefore, a 3.5-channel copter has three different controllable functions. A 5.5-channel copter has five controllable functions. A 6-channel copter has six functions.

Understanding Helicopter Parts.

Now the consumer knows that different radio channels control different functions, it is time to understand how those functions control the helicopter parts. Helicopters move due to their motorized blades and controlling mechanisms called gyros.


“Rotors” refer to the technical name for the blades of a helicopter. The number of channels determines the helicopter rotors. A 3-channel copter, for example, has two rotors. One is the large main rotor directly above the cockpit. The second is the smaller tail rotor located at the end of the tail. The main rotor controls speed while the tail rotor controls direction.

The 5-channel helicopters and more complex types include a third set of rotors. These blades are on top of the tail rotor and run parallel to the main rotor. This allows the helicopter to go straight up and down

Keep in mind that in some helicopter setups, the blades are all stacked right on top of each other. For example, many 3-channel helicopters put the tail rotor directly above the main rotor. Technically this is a tail rotor even though it is no longer located on the tail. The collective term for these types is “toy grade helicopters,” and they work well indoors.


The gyro lies inside the helicopter, and this part helps give the helicopter additional control. The 3-channel and 5-channel helicopters have no way to control the gyro. It reacts to conditions, such as the wind spinning the tail too much, and automatically adjusts the weight in different parts of the toy. The 6-channel and up helicopters allow operators to control the gyro.

3.5-channel Helicopters.

The 3-channel helicopter falls into the toy grade coaxial helicopter range. This does not mean that only children use it. What it does mean is that this is a beginner’s model. It is slightly more complicated than a 2-channel type but less complicated than a 4-channel one. It has three rotors: a main rotor, tail rotor, and parallel rotor.

Control Features.

The first channel on the helicopter controls the thrust, or speed, of the toy. All radio-controlled helicopters, regardless of how many channels they have, dedicate one channel for thrust. Sometimes collectors refer to thrust as throttle, but rest assured they mean the same thing. The main rotor blades control thrust by speeding up or slowing down.


“Yaw” is the term for the turning motion made by the helicopter. The toy yaws either to the right or left. The tail rotor controls the yaw of the helicopter. GYRO Hercules Unbreakable 3.5CH RTF Electric RC Helicopter


Helicopters are not airplanes and therefore have a different range of motion. These unique machines move vertically up and down when needed. The technical term “elevator” refers to this up and down motion, and this is the third control feature of 3.5-channel copters. A small rotor in the tail, which is parallel to the main rotors, allows for this movement. This feature also gives the helicopter the ability to hover in place. Hercules Unbreakable 3.5CH RC Helicopter tail rotor controls

5.5-channel Helicopters.

The 5-channel helicopter has two additional functions over the 3-channel helicopter. Of course, this model also shares several similarities in its design. It has the throttle, yaw, and elevator functions of the beginner model, but the two additional functions classify this as an intermediate type toy or hobby grade collective pitch helicopter. This means it flies indoors and outdoors due to the fact that its tail rotor is actually on its tail.

Helicopters have the ability to move side to side very rapidly in an aileron maneuver. In the real world, pilots perform the aileron maneuver to avoid enemy fire. For hobbyists, the aileron function is fun to use because it looks impressive. The tail rotor controls aileron movements just like the elevator maneuver. Hercules Unbreakable 3.5CH RC Helicopter tail rotor controls

Collective Pitch.

Hobby grade helicopters don’t have flat main rotor blades. The blades bend around a central point. This allows the rotor to tilt, giving it the ability to use collective pitch. This allows the helicopter to rapidly accelerate and perform tricks like loops and dives.

Comparing the 3.5-channel vs. 5.5-Channel Helicopter.

Both of these types have their positive and negative aspects. One model is not suitable for all. Examine the different features to see which one fits best.

Radio -controlled helicopters are not just for kids, and adults have plenty of fun exploring this hobby. However, this does not mean that every adult has to rush out and buy the most expensive RC helicopter he or she finds. Sometimes starting off small is better, and that’s where the 3.5-channel RC model comes in handy. It is a great indoor copter for adults and children. GYRO Hercules Unbreakable 3.5CH RTF Electric RC Helicopter

Those who already have some flying experience under their belt may want the extra functionality of the 5-channel model. The 5.5-channel RC helicopters work both indoors and outdoors and introduce consumers to the world of hobby grade helicopter flying. Explore the different models and find the ideal product that is fun, fast, and affordable for any budget.
